3om`ms. (o1. 43-11) l whereby the battery positioned in the oat is'easily removed and replaced.

These and other objects will hereinafter be more fully explained,reference being had to the accompanying drawing forming a 'part of thisspecification, and in which like characters will apply to like parts inthe different views.

Referring to the drawing:

Fig. 1 is a top or pian view of the float.

Fig. 2 is,a sectional view taken on line 2-2 in F18. 1.

Fig. 3 is a sectional view taken on line 3 8 in Fig. 1, illustrating theposition of the positive side of the switch.

Fig. 4 is a modification for the actuating means to break the currentand also as `uid tight sealing means for the switch cavity.

Fig. 5 is an end view of the sleeve, the spring, battery and contactmembers removed.

Fig. 6 is an enlarged perspective view of the negative contact element.

This invention herein disclosed consists of a float body I parabola inform and being bored axially through its major axis. The bore at theblunt end of `the oat is funneled as at A, the annular wall of which isarcuate in cross section radially, by which means a radiant surface isprovided as a result of light rays from a lamp later described.Positioned in the bore adjacent its funneled end is a translucentthimble element 2, iitting snugly therein as fluid tight sealing meansfor its respective end of the bore.- the closed end B protruding a shortdistance into the funneled portion of the bore. The other end of thebore has a sleeve 3 inserted therein uid tight, the end portion of whichis threaded internally to receive a plug 4,'threadedly engaging iresting upon a helical spring 'I that is carried by a mediallypositioned head 8 integrally joined to the sleeve. The upper end of thebattery extends into the skirt C of a lamp socket 9, the

socket tting closely within the thimble 2, funcf tioning to expand thewall of the thimble to tight engagement with the wall of the bore. Inother words, the socket element may be inserted with in the thimbleprior to the insertion of the thimble into the bore at the time ofassembly. The socket 9 is axially bored and threaded to receive thethreaded base. III of its lamp, by which means the lamplis in contactwith the upper end of the battery and is enclosed fluid tight by thetranslucent thimble. The end of the socket adjacent the lamp isdepressed and has a reector I to intensify the light beams produced bythe lamp.

The switch mechanism consists of a member II, having a right angle bendon the lower end thereof as at D, the other end of the member beingreduced to form a shoulder E on each side thereof. The reduced portionis insertible through aperture F of the sleeve head and is adapted tosecure the spring element I to the head by being bent over the base coilof the spring as at G. The element II is the negative side of theswitch. The positive side consisting `of a member I2, the .lower endportion of which,

as at H, is bent at right angles towards the negative side, while theupper portion thereof extends throughk slot J and from'thence upwardinto contact with the skirt of the lamp socket member. The positive sideis insulated from the sleeve and head by an appropriate insulatingmaterial and has means to adhere the same to the sleeve as shown at I2',said insulation being a lining for slot J, While one side extends fromthe inner end of plug 4 to the upper extremity of the sleeve to avoidcontact of member I2 at any point along the sleeve.

As closing means for the negative and positive sides above described, Ihave positioned a ball I3 on the inner end of a stem I4 that axiallyextends through said plug 4 and is free to slide therein, the ball beingadapted to move to and from contact with the adjacent ends of the rightangle bent portions above described, to make and`break the currentbetween the lamp and battery. 'Ihe said ball is. tensioncd upward fromcontact by a spring I seated in the plug 4 as shown. The circuit isclosed through the medium of a jerkon a line I6 that is secured to aneye K formed on the outer end of the stem I4.

It will be understood that line I6 extends upward from its loopedposition in the eye K and passes through the eye L of an ear I1 that isse cured to the float near the top thereof. A similar apertured ear isoppositely positioned on the doat with respect to the 'axis thereof,towhich is secured a cord il, having a ring l@ attached to its free endthroughwhich the line i6 extends and is thereby anchored in axialalignment with the float. It will be noted that the line Ilv snuglyengages in its respective ear aperture L as frictional binding means tocarry the load of) the oat and to provide in the line a slack portion asat M to permit free movement oi the stem when actuated to make and breakthe current as abovedescribed. In other words, the jerk of a shor thelike upon the hook i6' will causeL the lamp to light, which isconvenient for night ilshing.

in Fig. fi is shown a substitute for spring it consisting of a disk 2li,the disk having a marginal portion thereof adjacent its periphery snugiyengaging between the inner end of plug 4 and a flange 2| spaced inward ashort distance from the outer end oi sleeve t by which means the disk ise, iiuid tight sealing means for the switch cavity. The disk iscentrally apertured to receive the ball stem it vulcanized therein, andto insure snug engagement there is secured to the stein on each side ofthe disk, flange elements 22, by which arrangement the disk will dendown ward by jerk on the line, closing the circuit and then rebound toits normal straight position breaking the circuit, i

While il have shown and described a oat,` parabolic in form, I do notwish to be restricted to such alone, as the iorrnfmay be' spherical orotherwise, and such other modincations may be e as lie within the scopeof the appended claims,

Having fully described my invention, what I yciaiin as new and desire tosecure by Letters Patent is:

i. in a nsh line oat, a body axially bored, the bore being iunneled atone end thereof, a translucent thimble inserted in the iunneled end-ofthe bore, a skirted lamp socket positioned in the thimble, a lampengaging in the socket, the lamp of the sleeve, a switch mechanismcarried by the sleeve, and a line to actuate the switch.

2. In a sh line float, a body axially bored, one end of the bore beingfunneled upwardly and outwardly, a translucent thimble, one end of whichis closed, the other end being open, a skirted lamp socket positioned inthe thimble, said socket having a reector in the end opposite its skirt,a lamp carried by the socket adjacent the reflector, the thimble beinginserted in the bore adjacent its funneled end, the open end of thethimble being inward, a. sleeve in the lower end of the bore, a batterypositioned in the bore and carried by the inner end of the sleeve' andthe skirt of the lamp socket, a head positioned in the sleeveintermediate of its ends, a spring seated on the head as tensioningmeans for the battery toward the lamp, negative and positive currentconducting elements extending through and from' the head opposite thespring, one of said elements being in contact with the spring while theother element extends upwardly and outwardly from the sleeve and incontact with the lamp socket, said iast-named element being insulatedfrom the sleeve and head, a plug in the outer end of said sleeve andserving as a fluid tight closing means therefor, a ball and a stem, thestem carryingthe bali in working relation to said current conductingelements, the stem being axially carried bythe plug and slideabletherein, and a spring to space the ball from contact vwith said currentconducting elements.

3. In a sh line oat, in combination, a oat body axially bored, a lampand socket, 'said socket having a skirt, translucent means enclosing thelamp, said means and socket engaging Huid tight in one end of the bore,the socket having a skirt inwardly extending with respect to the bore, a

sleeve positioned in the other end of the bore,

a battery positioned in the bore, one end of which is in contact withthe lamp and supported by the lamp socket skirt, the other end of thebattery being supported by one end of the sleeve, means in the sleeve tomove the battery in contact with the lamp, current conductors whichfunction as negative and positive sides of the current being carried bythe sleeve so that the positive side is in contact with the lamp socketsmrt, a switch to make and break the current,

a flexible disk, and a plug to secure said disk to the outer or otherend of the sleeve, said disk serving as means for permitting the switchto 'break or close the circuit.
